In the drawings, the embodiment of my invention illustrated includes generally a pick-up member or extensible trough section Ill having a shovel if. on the forward end thereofn for picking up loose materiali from the groundY Said extensible trough section is mounted for extensible or retractible movement with respect to a reciprocating' trough section IZ and said reciprocating and rextensible trough sections are reciprocably sup.- ported and guided in an. elongated frame i3; oon-- nected at its rear end to a base M, for-transverse ySeria-l No (Cl. Hi8- 14) movement about saidy base. Said base isy herein shown as. being mounted. on. wheels..l for movement about the but. is. adaptedto he held nlflxed relation with respect to. the ,ground by suitabie jacks, or the like., during. the loading operation.

The elongated frame [3., as herein shown. extends along .opposite sides oi the reciprocating trough-section l2 and the extensible trough section l0. Said frame is provided with. laterally spaced upright bearing members LE., 16, at its forward endhaving bearing engagement with. opposite sides oi said extensible trough section., for laterally swinging said extensible troughsection upon. lateral swinging 'movement of said frame. Said frame. is. mounted, adjacent its forward end, for transverse movement along. the ground, on a. pair of laterally spaced traction. devices [L l1. herein shown as being `traction wheels. adjustablgv mounted to move said frame in a longitudinal direction, or to swing. said frame from side to side. The support and drive,A to said traction wheels will be more. fully descrbedas -thssnecication proceeds..

The-connection from; the rear end ot sadframe to said hase issoxnewhat similar to that disclosed in Patent No. 2,280,0, issued to LoyD, Hagenbook on December 24, 194D, so will; only herein be described` insofar as necessary to maltef my pres.- ent invention. readily understandable. Said. conneetion` includes a connecting member I,!l,.herein shown as being pivotally connected to said `base for movement. abouta transverse axis. Said connecting member is provided. with a longitudinally extending slot lillE and a transversely extending slot 2l... Blocks Z2 and 23 have. vertical pivotal connection with. aplate 24. Said plate is secured to andy projects rearwardly from.. ther rear end of said frame, and saidy blocks have guiding engage.- ment with said slots, to guide said frame for movement aboutl a.y pair of. .longitudinally spaced parallel vertical axes. Said axes.v as herein shown, are theaxis of connection of an intermedi,- ate connecting troughsection 2i to a drive .trough section 2\6,..and the ot connection. ofv `said intermediate trough section to the reciprocating trough section Il..

The trough section. 16 may be attached to the forward end ot `a. shaker conveyer pan line not shown)l or may 4be, reciprocably driven from s.y

suitable independent drive .mechanismA mounted on the base- Iv4. As herein shown, said trough ccf tion connected tothe forward end ci a shaker conveyor pan line and is mounted on said hase at its forward end, for reciproe'ablewith. respect thereto. The: support im" trough section on said base includes a pair of laterally spaced, inwardly facing, V-shaped guide tracks 29, 29, which engage substantially V- shapedfaespfrollers 30, 30. Said rollers are mountedonbracket members 3l, 3l, extending laterally from opposite sides of said trough section, and are rotatable about vertical axes (see Figure 4). In a like manner, the forward end of n `herein be described in detail. Said extending.

means includes a pair of carrier members 33, 33,

l 'having'rfriction grip blocks 34 and 35 pivotally 'mounted thereinand adapted to engage the upper and ,lower sides of bearing plates 36, 36, pro- `"jecting laterally from andextending along the Pupper' edges. of said' extensible trough section. Said'carrier members are connected with a floatjing frame 31 by means of links 38 and 39, which Yiloativng frame is reciprocated with the recipro- -catingtrough section I2. Y

fThe floating frame 31 includes a pair of side iframe members 40,40 which are pivotally conf'nected'at their rear-ends to opposite sides of a U-frame 4I, secured to and extending across the bottom of and upwardly along opposite sides of the forward portion ofthe reciprocating trough "section I2. Thel connection between said side frame membersincludes pivotal pins 42, 42 extendingV through brackets 43, 43, formed on op- 'posite sides of said U-frame.

The forward end of said floating frame is slid- "ablysupported on the bearing plates 36, 36 by "means of two pairs of parallel spaced flanged rollers 44, 44, mounted in opposite sidesfof a U- yfsliaxanedjforward vendVv portion "45 of said floating frame and engaging the upper and lower sides "ofthe-bearing,plates 36,-36. f The'links 38,36 extend `in a downwardly and rearwardly inclined''directionl from the upper 'endsofthe'carrier members 33, 33 and are slidably mountedY on *aV transverseshaft- 46. Said lshaft is journaled `in opposite -sides 49,4!)U of the fframe 31. Cam members 41, 4-1 are mounted on 'said shaft and are engageable with rollers 48, 46 mountedl on saidlinksfor holding said links from slidable movement with respect to said shaft, to

'cause said llinks to exert a pulling force on the upper ends of said carrier members ina direction `to engage the grip blocks 34 and 35 with the bear- 'ing plates 36, 36 upon the return strokes of the -conveyer, and'to'exert a force von said carrier lmembers-in a, direction to disengage said grip blocks from said bearing plates during the for- -ward strokes of the conveyer.v Said cams are engaged with or disengaged from said rollers by means of a hand lever 49 and a yieldable link V5I).

The links 39, 39 are of a, yieldable construction to cause the grip blocks 34 and 35 to release from `the bearing plates 36, 36 upon the forward 'strokes of'the conveyer, when said extensible vtrough section engages an obstruction and said links are extending said extensible trough section. Said links are mounted for slidable movement with respect to a transverse shaft I, journaled -in opposite sides of the frame 31.# Later-ally s'pa'ced cam members-52, 52 are mounted on said shaft and are engageable with rollers 53, 53 mounted on said links, for holding said links from slidable movement with respect to said shaft, to cause said links to engage the grip blocks 34 and 35 with the bearing plates 36, 36 upon the forward strokes of the conveyer. Said cams are engaged with or disengaged from said rollers by means of a hand lever 54 and a yieldable link 55.

. 'I'he base I4, as herein shown, is mounted at its forward end on a pair of wheels 56, 56, which are freely rotatable about coaxial transverse axes, and is mounted at its rear end on a pair of laterally spaced power driven wheels 51, 51, which are keyed to a transverse shaft 58. Said shaft is journaled in said base and is selectively driven from a motor 59, on said base, by means of a worm and worm gear drive generally indicated by reference character 60, and a suitable clutch 6I, herein shown as being a jaw clutch. Theworm of said worm and worm gear drive is driven from the rear end of a longitudinally extending shaft 62, which shaft in turn is driven from said motor by a reduction gear train generally indicated by reference character 63. Saidbase may thus be moved by power in a longitudinal direction, reversal in they direction of movement of said base being effected by reversal in the direction of rotation of the motor 59.

The drive to the traction wheels l1, I1 includes a universal coupling 64, keyed to the forward end of the shaft 62. Said universal coupling has driving connection with a longitudinally extending shaft 66, by means of a shaft 61, a sleeve 68, lslidably engaging said shaft,v anda universal coupling 69 (see Figure l). Said longitudinally extending shaft 66 is journaled in a tubular'side frame member 61a of the frame I3 and extends therethrough. l

A bevel gear 16 is keyed on the forward end -of they longitudinally extending shaft 66 and serves to drive one traction wheel I'I (see Figure 7). The other traction wheel I1 is driven from a bevel gear 1I, keyed on the shaft 66 intermediate its ends '(see Figure 3). Said bevel gear meshes with and drives a bevel gear 12 on a transverse shaft 13. Said transverse shaft is journaled in a cross member 14 of said frame on the hub of the bevel gear 12 and the hub of a bevel gear 15, keyed lon the end of the shaft 13, opposite from the bevel gear 12. Said last mentioned bevel gear meshes with and drives bevel gears 16 and 16a freely vmounted on a longitudinally extending shaft 11, which is journaled within a side frame member 18 of the elongated frame I3, opposite from the side frame member 61d.

A suitable clutch, such as a jaw clutch 19, is provided to selectively connect either of the bevel gears 16 or 16a to the shaft 11, forselectvely driving said shafty in reverse directions. Said clutch may be operated by a suitable system of levers ofany Well known'type (not shown), for

connecting the bevel gear 16 with the shaft 11 `and .driving thel right-hand traction wheel I1, in

the samedirectionY Aas the left-hand traction wheel when said traction.wheels are positioned to extend longitudinally of the loadingmefchanism, and lfor disconnecting said gear from said shaft and connecting the gear 16a with said shaft for reversing the direction of rotation of said shaft and driving the right-hand traction wheel in the samedirection as the left-hand traction Wheelf'when said Wheels are positioned to swing theloading mechanism laterally with respect to the workingface. 1 I

Yuri-vt from the forward ena ofthe shaft 11' to the right-hand traction Wheel l1 is the same as the drive from the forward end of the shaft 16 to the letvhand traction wheel, sov the drive to theleft-hand traction device only will herein be described.

The bevel geark meshes with and drives a angular-ly forwardly and outwardly from the fshaft 66. The housing l1 is secured to the ira-me and is provided withan enlarged forwardly projecting portion` 89 of a. semi-spherical form tion, which semi-spherical portion forms a sup port and mounting for a traction Wheel lli'.

-' 'The traction wheel -il is of s. drum-likefcon- -struction with a closed outer end 90 (see Figure '7) Said traction dew'ce encircles the outer portionoet the spherical forward portion of the housing 81 and is provided with a packing member 91| at its inner end, which is ofan annular for- -mation and which has wip-ing engagement with the periphery of said spherical supporting porition, to keep dirt from the inside of said traction lwheel.

Said packing member is mounted in a ring 93, threaded within vthe inner endofy said vtraction wheel, and" isY retained in said ring by means of anannular member 94, secured to the inner end ofv said traction wheel.

The mounting for the traction wheel Iilk on the forward spherical portion 89 of' the housing I1 'includes a vertical shaft 95, journaled within said semi-spherical portion of said housing and having an axle support 96 jou-maled thereon, intermediate the ends of said shaft (see Figures 5 and 6). Said support as herein shown has an integrally formed stud 5T, projecting outwardly therefrom, which is journaled Within' a boss 99,

projecting inwardly from the closed outer end .90 of' said traction wheel, and which forms an axle forsaid traction wheel. Said traction wheel muy thus pivotally move with respect to said housing about a vertical axis, to movethe elon- .gated frame il and the extensible and reciprocattrough sections l0 and I2 either in a longitudinal direction or transversely with respect to the base I4. Said traction wheels, as herein are pivotally moved about a vertical; axis by bandi-but suitable steering mechanism of any -welli-known construction may be provided for turning said traction wheels, if desired.

The drive from the shaft 85 to the left-hand 'traction wheel i1 includes a bevel gear |00 keyed on the forward end of said shaft and meshing with a bevel geen` I'Bl keyed on the vertical shaft lli, just above the .axle support 96 (see Figure 5).

A worm |93' is keyed on and driven from said shaft and is disposed in an open portion of said axle Support, adjacent the lowerend thereof, and meshes with and drives a Worm gear |84, suitably jorunaled in said axle support. Said Worm gear is-mounted on `shaft |05, which is journaled 'witlrin said axle support and serves to drive said short, A spur gear |06 is keyed on 'the outerV end of saidshait and meshes with an internal gear W'F, secured to the inner periphery of said traction wheel, for driving said traction wheel.

Itmaybe seen from the foregoing that when it -is desired to move the entire loading mechanism about the mine or into the working place,

that the traction wheels i1, |`1 Amay be positioned for rotation about transverse axes and that` said traction wheels together with the traction wheels fio 51, 5T may vmove apparatus in a longitudinal direction. The :direction of movement of said loading device may be reversed. re-

versng the direction of rotation of thexmotor 5S. When it. is desired' to swing the extensible trough section lll. and shovel il laterally the ltraction wheels lhilare pivoted' about the axis of the vertical shafts y95, by hand, until they' 'transversely positioned with .respect .to

trough section,v 'and the direction, of rotatimr'of the shaft Tl is reversed byV the clutch 11,9; so both Awheels will rotate in the same direction. Power is `then applied to said traction wheels through the motorr 59' and shaft. 65, and reversal in swineing movement otsaid extensible trough section is eilectedby reversing .the direction. of rotation ofsaid motor'.

Since a greater part of the reduction. gearing, for driving the traction wheels IJ, il from. the shaft 6B is withinv the limits o! said. traction wheels; sincethe reactions in ahorizontal direcvwill' be understood that the construction thereof and the arrangement ofthe various kparts may-be altered without departing from the spirit and scope thereof. Furthermore, I do not wish to .be construed as' limiting my invention to the specific embodiment illustrated, excepting as it may llie limited? in the appended claims.
